Application filed February 10, 1911. Serial No. 607,796.

To all whom it may concern:

Be it known that I. Enxns'r DE LA SHA- LERI, a citizen of the UnitedStates, residing at Pittsburg. in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inStreet-Cleaning Machines, of which the following is 'a specification.

The present invention comprises a machinedesigned particularly forcleaning streets.

. The machine embodies a suitable truck adapted to be drawn by horses orother draft animals, or to be propelled by means of a motor,mechanism-being provided for loading material scraped or swept from astreet intothe body of the vehicle and other mechanismbeing utilized tospread and pack the material as it is elevated and deposited in thevehicle body.

The invention also includes special devices for spreading the material,in the operation of the machineas above described, and pe culiar meansfor adjusting the latter device whereby, under certain conditions, theymay be employed for the purpose of facilitating unloading of thevehicle.

Another feature of the invention resides in the special means employedfor remov ing dirt, snow, or other foreign matter from the street andelevating it for deposition in the body of the vehicle. 7

For a full understanding of the present invention referenceis to be hadtothe following detail, description, claims and drawings wherei'n-Figure 1 is a top planview of a machine embodying the essential featuresof the present invention, a certain portion of the top of the machmebeing shown insect on; Fig. 2 is a side elevat on of the same; Fig. 3-

Throughout the following description and on the several figures of thedrawings. similar parts are referred to. by like reference characters.Specifically describing the invention and referring .to the drawings, 1denotes the body of the machine which may be ofany suitable type builtwith a View of containing material, such as snow, dirt, or other foreignmatter that may be gathered from streets or similar places. The body 1-is mounted upon suitable trucks and ground wheels 2 and, as abovementioned, the machine may be propelled by a motor, as shown, or pulledby draft animals, if desired.

At the front end of the machine is mounted an elevator in the form of asuitable carrier 3 supported upon a frame frigidly secured to the body1;

Pivoted to the lower end of the elevator t at "5 is a scraper 6consisting of a suitable frame equipped atits frontend with a scrapingblade 7, the latter being adapted to- I Under some conditionsit may bedesired to provide the scraper'6 with a sweeper or brush 13 and thelatter is secured just in advance of the scraping-blade otherwisesecurely fastened to suitable fixtures at the front portion of the.scraper.

The scraper 6 is supported, when in its operative position-by theyieldably monntby meansof the frame parts 1 1 which are bolted or 106link 12v with the frame orbody of the scraper 6.

ed wheels15 the latter being jonrnaled di-- 16 supported in guides 17attached to opposite sides of the scraper t3. Springs are so arranged atopposite sides of the scraper 6 as to cooperate with the bars 16" toresiliently or yieldablv support the wheels 15. thus affording aresilient mounting" so to speak. for the scraper 6 permitting thelatter. to accommodate itself to any unevenness in the surface overwhich the machine pa se there y increasing its. etliciency.

It will be apparent that the. material carried upward from the street orother surface beingcleaned by means of the elevator 3 willhe dumped intothe body 1 of the mat chine. In order to spread this material as it isdumped into the body 1; special means. are employed and the same willnow be described. l d'ounted upon a shaft 19 supported in snilablebearings and arranged transversely on the body 1 are driving wheels 20,The shaft 19 is driven bya motor 21 or any equivalent means. said motorbeing connected bv the driving belts or chains 22 and with drivingsprocket or gear 2-1 on the shaft 19. The carrier 8 on the scraper 6 islikewise driven by the motor 21. one of the shafts about which themember 8 pas es being connected by a suitable drivingchain 25 to theshaft 19. The driving wheels 20 are connected by pitman rods 26 tolateral arms 27 projecting outwardly from the sides of a U-shapedspreader frame 28. The spreader frame 28 is arranged intermediate theends of the body 1. and extends trans versely across the latter, asshown 'vmost clearly in the drawings. The sides 28 of the spreader.frame are connected for' ertical sliding movement on the sliding guides.29, the latter consisting of inverted T-shaped members. the horizontalportions of which carry rollersEO and the vertical portions of.

which are channeled to receive th sides 28" of the spreader 28 andpermit vcrt cal movement of the spreader frame with respect to theguides 29 and the body 1.

'are adapted to operate in the horizontal guides 31 secured to theopposite machine. The lateral arms 27 of the spreader frame are not onlyconnected with the pitman rods 26 but the outer ends of said arms haverollers mounted rcon. r latter rollers operating in, the enoteiv v 33.The guides are arranged at opposi. sides of the body 1 and supported bysuitable brackets secured to the body 1. ho

:spreader frame 28 supports a plurality of spreading devices the latterbeing carried by the parallel. bars 36. The bars 36 are pivotallyconnected at adjacent ends to i the sides of the spreader frame, theouter most ends of the bars 36 having the outer most Spreaders pivotallysecured thereto,

and the intermediate spreader 35 being can I The rollers sides of the.

' is swiveled upoirthe intermediate portion of a the spreader frame 98.i

in rotating the same. Secured tothc intermediate spreader are horizontallifting bars 39, the intermediate portions of which are connected tosaid ihtermediate spreader, one end of each bar 30 being attached to therea'rmost spreader. Theiront .ends of the bars 39 extend throughbrackets 35 carried by the foremost front spreader 35. said.

damage to the smeaders'anay be avoided. For the abovepurpose the bars31} connecting the outermost spreaders with the spreader frame 28 may bemade insections, having the guidingsprings'at). in like manner theintermediate spreader-35 has yield- 1 ing rods 41 connecting it to thebar c From lthe foregoing it will'b'e understood.

that when'the machine is in actual operation the material l aded intothe. body 1 by means of the elevator 'and other mechm nism located atthe front end of the machine. lVhen the motor 21' is in operation thedriving wheels will be operated o as to reciprocate the spreader frameback and torth with respect to the guides A the spreader frame movestoward the rear end of the endless guides the rollers mean-- whiletraveling in said guide; 3. springs 42 arranged near ,the rear ends otthe guid...s 33 will engage the arms '27 of the. s: wlfer frame andraise the latter to cause the rollguides 33 as the spreader frame ipulled upwardly by the pitman rods 1'26. ll'hen the spreader framereaches the front limit oi? its movement with respect to the guides byreason of the shape of the latter guides, the spreading devices arepermitted .to drop ried by a vertical adjusting screw 57 which lcadedinto the body 1. whereby breakage or (ii-s39 to 'travel in the upperportions of? the a by a gradual downward and rearwt'u'd 1 during saidforward movement.

'vIt is to be understood that the body 1 may be provided with anysuitable-means for-facilitating the dumping or unloading of the materialcarried therein, any of the ordinary types of dumping mechanisms used ondumping vehicles being susceptible of use along the above lines.

Itis to be understood that the specific arrangement and construction ofparts hereinbefore described, and appertaining to the several mechanismsset forth, may be varied within the spirit of thminvention and the scopeof the appended claims.

Having thus fully described my invention, what is claimed as new is 1;In a street cleaning machine, the combination of a wheeled body, andmeans for spreading the material after the same is received in the bodyand comprising a spreader frame, guide members upon which said frame isadaptedto move, mean'sfor reciprocating the frame horizontally withrespect to the body of the'machine, spreading devices supported by thespreader frame, and means for raising the spreader frame uponits guides.at predetermined intervals of time as it is reciprocated.
